To all whom it may concern:

Be it known that we, HENRY LEIX, a citizen of Germany, Kingdom ofBavaria, residing at 315 Jay street, Brooklyn, in the county of Kingsand State of New York, and EMIL M. LOWY, a citizen of Kingdom ofHungary, residing at 184 East Seventyfifth street, New York city, in thecounty of New York and State of New York, have invented a certain newand useful Process in a Chemical Compound; and we do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

Our invention relates to compounds and more particularly to a compoundformed by certain ingredients or elements incorporated tofigether forthe production of a reliable and e cient pulley dressing to prevent theslipping and sliding of transmission belts.

The belt-dressings in use at the present time contain gum and resin andmust be applied to the belt at short intervals which means that. thedressing must be renewed after a few days or weeks of using. Furthermorethe present belt dressings in use lump up and make a black crust on thebelt and on the ulley so that the belt does not rest on the ull surfaceof the pulley causing the belt to slip and slide to a greater degreethan-before its use.

The main objects of our invention are as follows:

1. The dressing must be applied on the pulley and not on the belt and isusable for every transmission wheel, if of iron, steel, wood or paper. 7

2. When pulleys are dressed with our compound the machinery belts areabsolutely prevented from slipping and sliding off the wheels bytheadhesion of our compound which is three times as great as theadhesion ofdron or steel and twice as much as wood or aper, thereby agreater working be obtained and much energy will be ved under ordinarycircumstances where elts are used. There is a great loss of on beprevented by the use of our invention, for [by preventing sliding andslipping the Specification of Letters Patent.

3. Our compound dries u after applying and gets hard like stone a ter afew hours and need only be renewed after two or three years. Theadhesive properties of our compound remaln a ways the same until thecompound itself is worn off.

4. Our compound preserves the belt per-- feet-1y because it hardensthoroughly and does not close the pores of the belt. compound is fireand water proof and can be Worked in any temperature or in places whichare moisture laden.
